Abstract Rastall gravity, originally developed in 1972, is currently undergoing a significant surge in popularity. Rastall gravity purports to be a modified theory of gravity, with a non-conserved stress–energy tensor, and an unusual non-minimal coupling between matter and geometry, the Rastall stress–energy satisfying . Unfortunately, a deeper look shows that Rastall gravity is completely equivalent to Einstein gravity — usual general relativity. The gravity sector is completely standard… CONTINUE READING
